Germ layers are produced during gastrulation and are the initial tissue layers of an embryo. Sometimes they are called embryonic tissue layers. They will develop into all the different tissues and structures present in an adult animal. 1  Ectoderm is the outermost layer of cells.  Mesoderm is the middle tissue layer.
During the process of embryogenesis, blastula formation is followed by the gastrula, thus both represents a different stage of embryo formation. The blastula and gastrula are formed through different processes. The blastula is formed through blastulation, while the gastrula is formed through gastrulation. The blastula and gastrula are formed through different speeds of mitotic divisions. The blastula is formed through rapid mitotic divisions of the zygote, while slow mitotic divisions of the blastula results in the gastrula. In the process of blastula formation, the cells do not move. However, during the gastrula formation process, the cell masses move through morphogenetic movements. Unlike the blastula, there are three distinct germ layers that are present in the gastrula.
